In a book-length interview to be published next week, Pope Francis addressed gifts and challenges for clerical and religious vocations, among them the challenge of homosexuality in the clergy.

“The issue of homosexuality is a very serious issue that must be adequately discerned from the beginning with the candidates, if that is the case. We have to be exacting. In our societies it even seems that homosexuality is fashionable and that mentality, in some way, also influences the life of the Church,” the pope says in the book “The Strength of a Vocation,” set to be released Dec. 3 in ten languages.

In an excerpt from the book, released Friday by Religión Digital, the pope said he is concerned about the issue of evaluating and forming people with homosexual tendencies in the clergy and consecrated life.

“This is something I am concerned about, because perhaps at one time it did not receive much attention,” he said.

…“It’s a reality we can’t deny. There is no lack of cases in the consecrated life either. A religious told me that, on a canonical visit to one of the provinces in his congregation, he was surprised. He saw that there were good young students and even some already professed religious who were gay,” he related.

The pope said that the religious “wondered if it were an issue and asked me if there was something wrong with that. Francis said he was told by one religious superior that the issue was not “that serious, it’s just an expression of an affection.”

“That’s a mistake,” Francis warned. “It’s not just an expression of an affection. In consecrated and priestly life, there’s no room for that kind of affection. Therefore, the Church recommends that people with that kind of ingrained tendency should not be accepted into the ministry or consecrated life. The ministry or the consecrated life is not his place.”

We “have to urge homosexual priests, and men and women religious to live celibacy with integrity, and above all, that they be impeccably responsible, trying to never scandalize either their communities or the faithful holy people of God by living a double life. It’s better for them to leave the ministry or the consecrated life rather than to live a double life.”
